Answer
# Brief Explanations:
A chi - square test for goodness of fit is used to test whether the observed frequencies of different categories match an expected distribution. In option c, we are comparing the frequencies of fans in different sports categories (football, volleyball, tennis) in the US, which is suitable for a chi - square goodness of fit test. Options a and d involve relationships between variables (height - weight, class attendance - GPA) which are better analyzed with correlation or regression. Option b is about the impact of one variable on another (social media on stress level) and option e is about comparing means between two groups (sex differences in life expectancy), neither of which are appropriate for a goodness of fit test.
# Answer:
C. Are there more football fans in the US than volleyball fans or tennis fans?
